Research interestsMy goal as a scientist working for a state geological survey has been to link my professional interests with the practical needs of Wisconsin’s citizens, management/regulatory agencies, and the environmental consulting community. At the WGNHS, we propose and carry out applied projects having specific practical goals (see partial list below), but each project contains a research component. My areas of research include hydrogeology of fractured media, regional hydrogeology of Wisconsin, wellhead protection, and groundwater recharge.
During the past few years, the main thrust of my work has been to better understand how to characterize and model fractured aquifers and how to determine groundwater flow paths near water-supply wells developed in fractured aquifers.
Current projectsEvaluation of methods for assessing the movement of chemical and microbial contaminants through aquitards

CollaborationsAs an adjunct faculty member, I collaborate with faculty and students in the Hydrogeology Group in the Department of Geology and Geophysics, UW–Madison.
I work frequently with colleagues in the U.S. Geological Survey, Wisconsin Water Science Center, Middleton, Wisconsin.
On occasion, I co-teach short courses/workshops for the Midwest Geosciences Group. Courses include Advances in hydrogeologic analysis of fractured bedrock systems and Assessing groundwater movement and contaminant migration through aquitards: Hydrogeologic characterization and investigative techniques.
